With an elegant architectural solution that allows visually divide the living space without having to install additional doors are arched doorways. They allow you to move away from the standard model variants in the arrangement of accommodation. Round or arched shape characteristic arched doorways. Arch with a round opening into the following types:
“Classics” – the so-called arch with the proper radius of the arc;
“Modern” – is the rise in the performance of the arc arch;
“Romance” – edges are rounded arches with the right radius, and the average part is straight;
“Ellipsoidal” – arch is an arc made in the form of an ellipse, wrong or right.
Above the window or doorway rectangular shape is installed arch-shaped «transoms». In today’s construction market are ready to model arched openings, which are realized in the disassembled state. The kit includes panels to racks and arches, four poles, two arcs and decorative locks. Large decorative locks put down construction, and narrow curved – upward.
Arched doorways are plaster, brick, solid concrete and wood (pine, beech, oak). Some types of arched successfully used for installation indoors and outdoors (wood, brick and concrete), while others may only be used indoors (plastic, plaster, arches of particleboard and MDF).
Arches of brick.
In the so-called arched lintels most appropriate to use masonry arch, with the main requirement is the opening width greater than 2 m. The formwork, the core of which is cut along the contour of the arch centering is performed masonry arch. You must install racks on the wedge to the arch was fixed at the correct elevation and to facilitate the removal of a mark after the hardening of the solution used. Gauged brick with different width ends optimal for masonry arch, all the seams in such a case would be the same thickness. Canted form seams will, if masonry arches used common brick. Various boom lift and the radius of curvature characteristic arched openings.
Plank laminated arches will become a good alternative to capital brick arches. Glued uniform blocks, firmly attached to the intermediate nodes are used for the production of wooden arches. Archs without delays are four types. This type of arch provides no additional delays and the transfer of spreading out the arch on its feet. In the case of large loads on the supporting structures of the arch and wide spans require the use of additional delay.
Tightened bolts, metal plates are the best means for fixing joints archways. The necessary elements are cut from a template from a single piece of wood. Despite its seeming simplicity, this method is not without drawbacks. On the strength of the wood elements may affect properties of wood split into direct fiber in the ground bends. The second method involves steaming the elements of wood in metal molds or boiling.
There is also a third method, when in the field, involving prominent place of wooden elements, on a block of wood glued thin strips of wood. Using multiple bonded wood elements can be given any, even the most bizarre, shape. This method requires a long time and physical efforts.
Today, thanks to modern equipment and technology, perhaps the production of wooden glued structures of any length and shape. Manufacturing DCC provides bonding of several layers of lumber. During the production trying to observe the parallelism between the fibers all bonded items. Spruce and pine – the most popular materials for the production of glued wooden structures. In comparison with arches of solid wood, the arch of the elements of wooden glued structures have similar options for quality, but for aesthetic and physical-mechanical properties are not inferior to them.
Chipboard is used to perform corners archways. First you need to measure the thickness of the wall opening and to determine the radius of curvature. Following these procedures should make a triangle with one concave side. Coming from a template or drawing must be made counting of four triangles, which are subsequently cut from a tree or Chipboard. Then you have to saw the side and upper base bracket, for example, Chipboard, which should drill holes for attachment to the top of the doorway or ends. The next stage – the bond finished parts with screws or nails.
To determine where the holes under the dowels to the corner of the doorway should be ready to make the bracket. The holes for nailing the wooden plugs or dowels are drilled with a drill. Then you must use screws to attach the brackets to the corners.
The next step will need to saw of hardboard strip width equal to the width of the opening, then attach it to the concave parts of the brackets and nailed. To the top of the aperture can paste the relevant part of the strip. Normal construction putty used to glossing over hardboard joints and wall opening.
Attach the smaller efforts and achieve a similar result can be, using styrofoam 25 or 35 stamps for manufacturing arms.
